摘要: 实验室研究了不同条件制备的改性膨润土对赤潮生物及海水中DRP、COD的去除效应.结果表明:改性膨润土有效Al为1.5%时去除效应最好.经Na2SO4、Al2(SO4)3改性的膨润土在pH=5.5时去除效应最佳.改性膨润土的去除效率随Al/SO4比值增加而增加.改性膨润土添加絮凝剂醋酸甲壳质和Ca(OH)2提高了去除功效.Abstract: Laboratory research has been done into the effect of bentonite modified to remove red tide organisms and DRP.COD of the sea water under various conditions.The results show that the effect of bentonite containing efficacious Al 15% removes the most.The efficiency of bentonite modified by Na2SO4 and Al2(SO4)3 at pH.5 was the very best.The efficiency of bentonite modified increases with arise of adding Al/SO4 ratio.Removal efficiency of bentonite modified with additive coagulant acitic chitin and Ca(OH)2 increases.
